Default Re: Supercharger Pulley Modification

d) you will have overboost problems and will need a map clamp or something to resolve this issue
e) tuning for it

why not just machine the pulley down to 62 and then add a little spray to the car for a little more?
Thanks for your response jturkle, right now I'm planning to get it down to 62mm and only use it for track days, then put my C 3 pulley back on for daily driving.

I just wanted to know if the car could take a little more seeing as I'm only going to use it for a few seconds at a time on the track.

I think people have run 191 crank pulleys and/or run a 181 crank with a Code 3 pulley aswell, these combinations would surley be reving the s/c to around 16,000rpms?

I'm only doing this because I have a spare s/c pulley and it will be machined by a proffesional for free, I'm just trying to get the best scenario here. Maybe this will be my easy ticket into the 11s?
